WebAuth is a comprehensive system for authenticating web users. It relies on a login server to which users are redirected at their first attempt to access a protected web site and implements a protocol that uses whichever initial user authentication mechanism is convenient to establish the user's identity. Once the user has logged in to the login server, their identity is carried in a cookie set by that login server and they will not again need to enter their password until their credentials expire, even if they visit multiple different protected web sites.
